specific Embodiment 1

[0058] Such as figure 1 As shown, the ring network cabinet includes a cabinet body 101, and a gas box 102 is arranged in the cabinet body 101, and a solid-sealed pole 103 is arranged in the gas box 102, and the number of the solid-sealed poles 103 is three, and each solid-sealed pole 103 All extend along the vertical direction and are arranged along the front and rear directions. The front-back direction in this embodiment is the cabinet depth direction of the cabinet body 101 .

[0059] Such as figure 2 and image 3 As shown, a support beam 104 is fixed inside the gas box 102 , and the solid-sealed pole 103 is fixedly supported on the support beam 104 . The top of the gas box 102 is provided with an upper casing 107, and the top of the solid-sealed pole 103 is electrically connected to the upper casing 107 through a busbar; the bottom of the gas box 102 is provided with a lower casing 108, and the bottom of the fixed pole 103 is connected through a bus The rows are elect...

specific Embodiment 2

[0073] The difference from the specific embodiment 1 is that in embodiment 1, both the isolation static contact and the grounding static contact are embedded in the solid-sealed pole, and in this embodiment, the grounding static contact is embedded in the solid-sealed pole , The isolated static contact is set separately from the solid-sealed pole.

specific Embodiment 3

[0075] The difference from the specific embodiment 1 is that in embodiment 1, the isolated static contact and the grounding static contact are both embedded in the solid-sealed pole. In this embodiment, the isolated static contact is embedded in the solid-sealed pole , The static ground contact is set separately from the solid-sealed pole.

[0076] The specific embodiment of the embedded pole of the present invention has the same structure as that of the embedded pole described in any one of the specific embodiments 1 to 3 of the above-mentioned ring network cabinet, and will not be repeated here.

Abstract

The invention relates to a solid-sealed polar pole and a ring main unit using the same. The solid-sealed polar pole comprises a polar pole main body; an arc extinguishing chamber which is arranged inthe pole main body; a three-station moving contact which is movably assembled on the pole main body in a reciprocating manner, and is used for realizing isolation opening and closing operation and grounding operation of the solid-sealed polar pole in the reciprocating process. The solid-sealed polar pole also comprises an isolation static contact and/or the grounding static contact which are/is arranged on the pole main body in an integrated manner, wherein the isolation static contact is used for being conductively connected with a main bus and is matched with the three-station moving contactto realize isolation switching-on and switching-off operation of the solid-sealed polar pole; and the grounding static contact is used for being conductively connected with a grounding bus and is matched with the three-station moving contact to realize grounding operation of the solid-sealed polar pole. Due to the fact that the insulation performance of the solid insulation material is better than that of the insulation gas, after the isolation static contact and/or the grounding static contact are/is integrated on the solid-sealed polar pole, the insulation performance is improved, and the gas tank can be designed to be more compact under the condition that insulation of all components is guaranteed.

Description

technical field [0001] The invention relates to a solid-sealed pole and a ring network cabinet using the solid-sealed pole. Background technique [0002] RMU to SF 6 , N 2 , CO 2 , compressed air, etc. as the insulating medium, the main switch and the main conductive circuit are sealed in the stainless steel welding gas box. For example, an inflatable switchgear disclosed in the Chinese patent with the authorized announcement number CN205452934U, the switchgear includes a cabinet body, and an air box is arranged in the cabinet body, and a circuit breaker solid-sealed pole and a three-position isolating switch are arranged in the air box. The circuit breaker's solid-sealed pole includes an insulating solid-sealed shell, and an arc-extinguishing chamber is fixed in the insulating solid-sealed shell. The arc-extinguishing chamber has a moving end outlet seat and a static end outlet seat. The three-position isolating switch includes isolating static contacts. , grounding sta...
